Help with "Afternoon Tea Fingerless Gloves" ?

[JustNaz9]

Hello fellow craftsters! I'm in the process of making the famous "Afternoon Tea Fingerless Gloves" and was wondering if I could get some help with instructions? My grandma taught me to crochet but unfortunetly doesn't know how to read a pattern so I've had to teach myself that bit.

Row 10: Ch 2, work Stacked Arches patt in first 5 ch-5 loops, over next join between 2 arches work (3 dc, ch5, 3 dc)

It's the second part I'm confused about. where do I put the 3 dc, ch5, 3 dc?

I tried looking for pictures and couldn't find any helpful ones.

Thanks in advance for your help
